SAFETY-RAZOR.

Specification of Letters Patent.

- Patented. Oct. 29,1907.

Application filedhiaroh 9. 1907. Serial No. 361,536.

To all tvhom it may concern:

Be it known that I, .Tosnrrr J. S'rnmnARTnn, a citizen oi the United States, residing at Newark, in the county of Essex and State of New Jersey, haveinvented certain new and uSPilll Improvements in SafetyERazors;

and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being bad to the accompahying drawings, and E0 letters of referenc angle, with their cutting edges adjoining and forming pretcrablya slight space between them, whereby when either of the blades is being used, the other blade will act as aghanl so that the blade that is being used will not accidentally cut the operator.

The invention is further designed to provide a looking means for. securely fastening the blades in a casing, the locking'means being reversible, whereby one or the other of the'blades can be used, and this handle acting as a locking means when locking the blades, also secures the casing otlhe blades to the handle- This invention is also'de'signed to provide a razor, of this kind, that has no fine teeth or guards which are 'adapted'to catch the lather orthe fine hairs, and thus,

become filled, making the razor hard to manipulate.

drawings, in which Figure 1 is a' perspective view of the razor, and Fig.

2 is a section of the samc, showing the handle in elevation. .Fig. 3 is a section on line 3,3, in Fig. 2, and

Fig. 4 is a section on line 4, in Fig. 3. Fig. 5is affront view of a casing of a modified iorm. I

The casing of the razoris made with the end plates 10 which are preferably triangular or approximately so,

and the side'strips 11 project inward to' hold the outside a edge of the blade, and theseedge strips 1 1 are joined bythe top and bottom strips 12,- these strips covering the edges of the razor, except the cutting edge. Underneath the razor blade are the strips 13 which are connected with the inside top and bottom strips 14, these The invention is illustrated in the accompanying will be guarded against-entering the flesh of the oper-. ator. The inside strips l l have. projecting therefrom and underneath the blades, ,the strengthening strips 17, and th se strips are designed-to have atie or bar'18 join th m a slight distance back irom'the cutting edge' of the blades. This is done rather than have the strips 17 run up close under the cutting edges brfth blades, because there is thus no chance for the accumulation, directly under the cutting edges,of lather or-finediairs to alIect the efficiency of the razor.

ll desired, I may make the casing as shown in Fig. in which case I add the outside guards19' which terminate short of the cutting edges ofthe razor blades so as not to interfere with the cutting. These" strips 19 are used it extremely thin blades'are placed in the casing. The blades are preventedirom'approaching too close together by having the wings 16 on the ends of the back edge of each blade, these wings engaging the edge of the casing to limit the movement of the blades toward one another. 'On'eachside piece'10 is a hook 20 which forms abearing for the ends21 of the bar 22. In the center of this bar is an enlarged portion 23" with 'a screwthreaded recess. Into this screwthreaded recess is screwed the shaft 24 ot the handle, this shaft 24 having a thread 25 to work in the nut 23 so that when it is screwed up tight, the upper edge of the shaft 24 will engage the back edge of one blade of the razor. The handle is provided, below the shaft 24, with an enlarged portion 26 slightly tapered, and which has a flange 27. When the end of the shaft 24 engages the back of one razor blade, this flange 27 engages the edge, of the other. and the blades are thus se curely locked against any displacement, and are held firmly in place so that a rigid structure is in the hands of the person 'who is doing the-shaving. The tapered portion 26,-bearing on one razor blade, throws that edge of the casing out and it gives the casing and the blades the proper pitch for comfortable manipulation.

A handle portion 28 is suitably attached, and when one blade is worn, or for. any other reason it is desired to use the other, the handle 28 is twisted to unscrew the shaft 24 from the nut .23, and the handle can be swung oveig the ends 21 of'the bar 22 turning in the hooks 20, the handle being partially turned in Fig. 2,

'45 top and bottom strips 14, as shown inFig. 2, being where it is shown in dotted outline.

It will beevident that the handle can be entirely 1 turned over and again screwed up, this reversing the casing on the handle, and presenting anew blade.

This razor can be operated both by pulling it downward, by means of the handle, or by pushing it upward on the side-of the face, which is not possible with razors as heretofore made, and strokes only in one direction, acting to shave.

slightly curved to form an easy entrance for the blade. Between these strips on the inside and outside oieach of the triangular end pieces, are slid the blades 15-with' their cutting edges in close proximity and atan angle, 50 as shown in Figs. land 2, so that when one blade is I used, the other blade acts as a guard for it to prevent cutting, except to a certain depth, that is the blade that is being used to shave with take off the hair,- but guard to the other.

2. A safety razor comprising a casing, 21 pair of blades arranged at an angle in the casing with their cutting'edges adjoining, and a handle secured to the casing, the handle locking the blades in the casing.

3. A safety razor comprising a casing, channels, in the casing to receive a pair of blades, the blades being disposed at an angle to each other and with a slight space be tween their cutting edges, means for limiting the entrance, of the blades in the casing to insure a space between their cutting edges, and a handle attached to the casing.

4. A safety-razor comp'rising a casing, blades arranged in the casing at an angle to each other and with their cutting edges adjoining, and each bladebeing adapted to act vas a guardfor the other, and means for limiting the en- 7 trance of the blades in the casing.

5. A safety razor comprising a casing having e'nd pieces, channels in the end pieces, strips connectin'gthe end pieces at the top and bottom, blades'arranged in the channels and disposed at 'an angleto each other, and a handle secured to the casing and engaging the back ends ofthe blades to loci; the blades in the casing.

6. A safety razor comprising a casing, a pair of blades in the casing disposed at an angle to each other, their cutting edgesadjoining, a; handle secured to the casing and when so secured, engaging the back edges of the razor blades to secure-the blades in the casing.

7. A safety razor comprising a casing having end plates,

top and bottom strips connecting the plates, blades secured in the platesat an angle to each other, and guard strips blade to stiffen them.

8. A safety razor comprising a casing having end. lates, top and bottom strips connecting the end plates, a it of blades secured in the casing, guard strips underneath the blades and secured to the casing, ties connecting the guard strips at a distance from the cutting edge of the blades, and a. handle secured to the casing and when so secured, engaging the back edges of the blades to lock the blades in the casing.

9. A safety razor comprising a casing having a pair of blades disposed, at an angle to each other, a handle pivoted to the casing and rotatablethereon, the handle being re-' passing through the bar and engaging the back edge of one;

blade, an enlarged portion engaging the liack edge of the other blade, and a'handle secured thereto for its manual manipulation.

11. A safety razor comprisinga casing comprising end plates, edgoistrips on the end plates, top and bottom strips connecting the edge strips on the outside, inside top and bottom plates connecting the side pieces, guards or fingers projecting. from the inside and the outside top and bottom strips, and blades secured between the fingers and being disposed at an angle to each other,

In testimony, that I claim the foregoing I'have hereunto set my hand this 28th. day of February 1907.
